Extend to edge of the ruler far from the first end of rubber tip；It is carved with groove b in supporting plate upper surface；Groove b is by protractor origin along a certain
Graduation mark extends to edge of the supporting plate far from the one end pullover b；Ruler passes through bolt b connection compasses radius ruler close to rubber tip
One end；Compasses radius ruler can be relatively rotated with ruler.
The utility model is also characterized by:
Ruler offers supporting plate accommodating groove in a thickness direction.
Ruler offers compasses radius ruler accommodating groove in a thickness direction.
The set-up mode of compasses radius ruler is that the upper surface of compasses radius ruler accommodating groove offers bolt hole a, and lower surface is opened
Equipped with bolt hole b, the scale starting point of compasses radius ruler offers bolt hole c；Bolt b sequentially pass through bolt hole a, bolt hole c,
Bolt hole b, and be fastenedly connected compasses radius ruler accommodating groove and compasses radius ruler by nut matched with its.
The set-up mode of protractor is that ruler side opens up fluted c, and protractor straight flange is stuck in groove c, and is glued
Knot.
Protractor upper surface is concordant with ruler upper surface.
The beneficial effects of the utility model are: collecting religion ruler, teaching compasses, religion protractor and compasses radius ruler in one
Body, when as compasses in use, joined compasses radius ruler, can be according to data come the circle of picture certain diameter, use is more efficient
It is convenient, and be easy to store.

Specific embodiment
The utility model is described in detail with reference to the accompanying drawings and detailed description.
As shown in Figure 1 and Figure 2, a kind of Multifunctional teaching aid, including ruler 1, are cased with pullover a2 outside 1 one end of ruler, in pullover a2
It is nested with rubber tip 3；1 other end of ruler passes through one end of bolt a4 connection supporting plate 5, and ruler 1 and supporting plate 5 opposite can turn
It is dynamic, pullover b6 is cased with outside 5 other end of supporting plate；It can nested chalk 7 in pullover b6；Pullover a2, pullover b6 are detachable；Ruler 1 is remote
One end from rubber tip 3 is also reversely connected with transparent protractor 8；It is carved with groove a9 in 1 upper surface of ruler；Groove a9 is by protractor
8 origins extend to edge of the ruler 1 far from 3 one end of rubber tip along 0 graduation mark；It is carved with groove b10 in 5 upper surface of supporting plate；Groove
B10 extends to edge of the supporting plate 5 far from the one end pullover b6 along a certain graduation mark by 8 origin of protractor；Ruler 1 is close to rubber tip
3 pass through one end of bolt b11 connection compasses radius ruler 12；Compasses radius ruler 12 can be relatively rotated with ruler 1.Ruler 1 is in thickness
Supporting plate accommodating groove 13, compasses radius ruler accommodating groove 14 are offered on direction.
The set-up mode of compasses radius ruler 12 is that the upper surface of compasses radius ruler accommodating groove 14 offers bolt hole a, following table
Face offers bolt hole b, and the scale starting point of compasses radius ruler 12 offers bolt hole c；Bolt b11 sequentially pass through bolt hole a,
Bolt hole c, bolt hole b, and carried out compasses radius ruler accommodating groove 14 and compasses radius ruler 12 tightly by nut matched with its
It is solidly connected.
